DUMP-CAR.

Specification of Letters Patent.

Patented May 12, 1914.

Application led September 11, 1912. Serial No. 719,829.

To all whom t may concern Be it known that I, RICHARD VEBB BUR- Nn'r'r, a citizen of the United States, residing at the city of Montreal, in the Province oi Quebec and Dominion of Canada, have invented certain new and useful Improvements in Dump-Cars; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates particularly to dump cars of the type disclosed in my United States Patent application Serial No. 655253, filed October 17th, 1911.

My invention consists of the combination of a hopper for a railway car having a door adapted to close to a position in an approximately vertical plane to control the discharge end of the hopper, the hopper having pockets in the end edges of the door opening, a hinge joining the door to the floor of the hopper and comprising a pair of hinge members one of which is formed with a series of alined slots and carried by the floor member, the other having a series of tubular tongues for engagement with the slots and carried by the door, the door having end flanges, the pockets in the door frame receiving such flanges, and clamping devices carried by the door frame and acting upon the free side edge of the door when closed.

The invention further consists of the construction, combination and particular arrangement o'f parts herein described and pointed out in the claims.

For full comprehension, however, oit my invention reference must be had to the aecompanying drawings forming a part of this specification .in which similar reference characters indicate the same parts, and wherein:

Figure 1 is a vertical sectional view of a dump car hopper taken on a line extending transversely relatively to the car; Fig. 2 is an enlarged detail sectional view of the hinge; Fig. 3 is a detail ltransverse sectional view of one of the flanged ends of the door and the pocket in the door frame engaged thereby taken on line A A Fig. l; Fig. 4t is a detail elevation of the hopper with the door closed; Fig. 5 is a perspective View of the hinge and portions of the door and hopper floor, the door being thrown open; Fig. 6 is a detail elevation of the means for locking the clamping device in position holding the door closed; and Fig. 7 is a detail perspective view of the clamping device.

The hopper floor is indicated at and the ends at c, the floor extending from the center sill l to within close proximity of the vertical plane of the side sill c, thus placing the discharge opening approximately perpendicularly. The dump door f is hinged to the floor member and its ends are flanged as at g and engage pockets g in the front edges ot' the hopper' ends While the free side edge of the door engages a flange s upon the side sill, and it is clamped in its shut position, after having been manually closed, by a rock-shaft 0 carrying a series of dogs n. This type of door forms an extension of the floor of the hopper and throws the lading a considerable distance laterally, which is an advantage in that it is thrown clear of the rails. lVith doors of this type and applied in the manner described to hoppers through which granular commodities are discharged, while the free edges are effectively closed against leakage by the clamping appliance described, the hinged edge has been heretofore a source of trouble owing to leakage due to wear, imperfect fitting, and, in some cases, inherent weakness unless constructed from extra .heavy materials.

In order to obviate the defects just described the hinge connection between the dump door and the floor member is effected by a pair of hinge members 79 and r. The hinge member r is formed with an alined series of slots a near its lower edge which is bent downwardly to tubular form, and the hinge member p upon the inner edge of the door has a series of tubular tongues p engaging the slots u, and a pintle 772 passed through the tubular edge of the floor and the tubular tongues braces the hinge members in hinged relation and is riveted as at p to the hinge member upon the floor.

A hinge et the form described effectively prevents leakage between the door and hopper floor member, and is strong and durable and of simple construction.

IVhat I claim is as follows 1. In a hopper for dump cars, end plates, hopper sills at the opposite sides of the top thereof, an inclined floor member extending :trom one of said sills to within close proximity of the vertical plane of the other of; said sills; a door ttor closing the opening inclosed by the end plates the floor and the last mentioned sill, and a hinge pivotally connecting the door to the hopper and consisting of a member having a series of alined slots and a member having a series of tubular tongues for engagement with the said slots.

2. In a hopper for dump ears, end plates, hopper sills` at the opposite sides of the top thereof, an inclined floor member extending from one oi' said sills to Within close proximity of the vertical plane of the other of said sills; a door for closing the opening inelosed by theend plates, the floor and the last mentioned sill; and a hinge joining the door and the floor member, and Consisting of a hinge member having a. series of alined slots near one edge thereof, and a hinge member having a series of tongues of open tubular form for engagement with the slots,4

Y hopper sills at the opposite sides of the top thereof, an inelined floor member extending from one of said sills to Within elose proximity of the Vertical plane of the other of said sills; a door for closing the opening inolosed by the end plates, the floor and the last mentioned sill; and a hinge joining the door and the floor member, and consisting of a hinge member having a series of alined slots near one edge thereof, and a hinge member having a series of tongues of open tubular form for engagement with the slots; stiffening flanges upon the said hinged members, means securing one of such hinge me1nbers to the floor member and means securing the other hinge member to the door, a pintle pivotally connecting the hinge members, and means preventing displacement of the said pintle.

ln testimony whereof I have signed my name to this speoiiication in the presence of two Witnesses.
